MACHINE FOR TREATING HIDES OR .SKINS.

SPECIFICATION forming part of Letters'Patent No. 747,500, dated December 22, 1903. Application filed July 23, 1903. Serial No. 166,681. (No model.)

In the machine herein shown as embodying but which is passed over a pulley 1'2 on said this invention, a represents a bed-roll which shaft.

0 is provided with a covering 1), of rubber or From the above description it will be seen other yielding material, and is mounted in that the carriage c and the bed-roll ct are resuitable bearings in a reciprocating-support ciprocated by powerwhen the operator throws or carriage. The reciprocating support or the lever 8 so as to bring the toothed hub 0 carriage maybe made as herein shown, and into engagement with the toothed hub 19.

45 comprises two uprights c, mounted to slide Provision is made for automatically retainon guides 01, secured to or forming part of ing the toothed hub 0 in engagement with 5 the upper surface of the side frames e of the the toothed hub 19 until the carriage has commachine, and in the presentinstauce the uppleted its movement in one direction and to rights a are dovetailed onto the guides d, as automatically disengage the hub 0 when the carriage has reached the end of its movement in said direction. This result may be accomplished by mechanism as will now be described.

Referring to Fig. 1, the lever 8 is provided with a lug or arm 13, carrying a roller or wheel 14, which cooperates with a disk 15, having a recess 16 in its periphery. The disk is fast to a gear 18, which meshes with and is driven by a pinion 19 on one of the grooved shafts g-namely, the right-hand shaft viewing Fig. 1. The roller or wheel 14 is kept in engagement with the periphery of the disk 15 by a spring 20, connected with the lever 8 and with the shaft 21, on which the gear 18 is mounted. By reference to Fig. 1 it will be seen that when the lever 8 is thrown to engage the toothed hub 0 with the toothed hub 13 the gear 18 is set in rotation, and the disk 15 revolving therewith enables the operator to release the lever 8 and give his entire attention to manipulating the hide or skin, as the lever 8 is retained in the position into which it has been moved by the operator by the full periphery of the disk engaging the roller or wheel 14, thereby rendering the spring 20 powerless to disengage the clutch until the disk 15 has made a complete revolution and the recess 16 has been brought opposite the roller or wheel 14, at which time the spring 20 becomes active and moves the lever in the opposite direction and into the position shown in Fig. 1, thereby stopping the carriage at the end of its travel in one direction.

The power-operated bed-roll a has cooperating with it an operating-tool, which may and preferably will be a cylinder 25, provided with helically-arranged blades or vanes 26, adapted to the particular work to be performed by the machine. The bladed cylinder may and preferably will be manually operated, and to this end the said cylinder is supported by the upper end of vertically-arranged levers 27, fast on a rock-shaft or pivot 28, supported by the side frames 6 of the machine. Each lever 27 has its lower end connected to one link or lever 29 of a toggle mechanism, the otherlink or lever 30 of which is pivoted at 31 to a side frame of the machine. The toggle mechanisms are connected at their center by links 32 to a foot-treadle comprising, as herein shown, two levers 33, fast on a rock-shaft or pivot 34, supported by the side frames of the machine and having their front end connected by a cross-piece or footboard 35.

The toggle-levers 29 30 are normally out of line with each other when the treadle is elevated, and at such time the cylinder-carrying levers 27 are inclined backward and the knife-cylinder is in what may be termed its withdrawnorinoperativeposition. By depressing the treadle the toggle-levers are caused to approach a straightened position and the cylinder-supporting levers are moved so as to bring their upper ends forward, and thus cause the knife-cylinder to engage the work on the bed-roll It is to be observed that the operating tool or cylinder is under control of the operator, and the pressure of said cylinder on the work can be regulated by him to suit the particular kind of work being treated. In this manner he is able to cause the knife-cylinder to engage some work lightly and other kinds of work heavily, rendering the machine sensitive to the character of the work. The knife-cylinder may be driven in any suitable manner and is shown as having its shaft 38 extended beyond one side frame of the machine and provided with a pulley 39.

The machine may be provided with a fluted or other feed roll 40, having its shaft 25 journaled in uprights 41, attached to the side frame 6, one of the said uprights, as shown, having an opening 42, (see Fig. 4,) through which theshaft 38 of the knife-cylinder is extended. The feed-roll 40 cooperates with the bed-roll a, and for some classes of work the said feed-roll may cooperate also with an auxiliary feed-roll 44, supported in the carriage 0, so as to cooperate with the upper portion of the feed-roll 40, as shown in Fig. 3. The feed-roll 40, as shown, is supported in rigid bearings, while the auxiliary feed-roll 44 is supported in movable bearings which are acted upon by the springs 45, the pressure of which can .be regulated by the adjustingscrews 46.

The machine may be provided with a grinding mechanism, which may be made as herein shown, and comprises a carrier 47 for an emery or other grinding brick or block 48, which carrier is movable upon a suitable track 49, supported by the side frames.

In operation with the machine herein shown the operator throws the hide or skin over the feed-roll 44 when the carriage c is in its starting position,and arranges the hide so that substantially one-half of the same hangs below the bed-roll. The lever 8 is then thrown to apply the power to the carriage and the latter carrying the hide or skin is moved from the position indicated by dotted lines to that shown by full lines, thereby bringing the hide or skin into engagement with the feed-roll 40, which, in cooperation with the bed-roll a and auxiliary feed-roll 44, feeds the hide or skin past the knife-cylinder, which has at such time been brought into engagement with the hide or skin by depressing the treadle. The bed-roll a and feed-roll 44 are rotated in the same direction bya gear 51 on the shaft of the bed-rollandapinion 52 on theshaft of the feedroll engaging with and being driven by a gear 53 on the shaft of the feed-roll 40. When substantially one-half of the hide or skin has been acted upon by the knife-cylinder, the carriage c is returned to its starting position by the operator throwing the lever 8 so as to engage the clutch-hub 0 with the hub 19, and

when the carriage has reached the end of its backward movement it is stopped by the spring 20 disengaging the clutch 0 from the hubp. The hide or skin is then reversed and the machine again set in operation.

It is to be observed that after the operator has started the machine in operation both hands are free to handle the hide or skin. Furthermore, torn or poor hides or skins or those weak in structure can be treated with excellent results, as the pressure of the knifecylinder can be varied at the will of the operator.

Believing myself to be the first to embody in a machine of this character a bed-roll which is moved into and out of its operative position by power and an operating tool or cylinder which is moved into its operative position manually, I do not desire to limit this feature of my invention to the particular construction shown.
